Tick borne pathogens present a significant health challenge to animals and human because a single tick may transmit multiple pathogens to a mammalian host during feeding. The present study detected tick-borne pathogens from pet dogs. A total of 666 ticks were collected from 144 pet and sheltered dogs in Egypt from April to September 2018. For hemolymph, midgut and salivary gland smears 546 ticks were used as well as 360 egg smears from 120 female tick were examined by light microscope. The infected ticks were prepared for transmission electron microscopy (TEM). Ticks were identified; Rhipicephalus sanguineus. Light microscopy showed infection rates of 44.69%, 68.50% & 15.75%, in hemolymph, midgut and salivary gland, respectively. H. canis recorded the highest rates in hemolymph and midgut (35.89% & 49.82%, respectively), but Theileria spp. was the lowest (0.73% & 2.93%, respectively). In salivary gland smears, Babesia canis. was detected in 13.55% and Theileria spp. in 1.83%. Mixed infection in same tick was recorded in 4.76% &0.37% in midgut and salivary gland smears, respectively. Babesia canis stages were recovered from 15% of egg smears. R. sanguineus was natural infected by Babesia, Theileria, Hepatozoon and Anaplasma phagocytophilum as well as mixed infections of protozoa accompanied by a complicated sign of diseases and failure in accurate diagnosis.

Increased human mobility elevates the risk of exposure of companion animals travelling with their owners or imported from other regions to tick attacks. In this study, we highlight the potential role of dogs and cats taken for tourist trips or imported animals in the spread of ticks and tick-borne pathogens. The Rhipicephalus sanguineus tick, which is a vector of numerous pathogens causing diseases in animals and humans, is imported most frequently from endemic areas to many European countries. Additionally, alien tick species with high epizootic and epidemiological importance can be imported on dogs from other continents. Companion animals play an even greater role in the spread of autochthonous tick species and transmission of tick pathogens to other animals and humans. Although the veterinary and medical effects of the parasitism of ticks carried by companion animals travelling with owners or imported animals are poorly assessed, these animals seem to play a role in the rapid spread of tick-borne diseases. Development of strategies for protection of the health of companion animals in different geographic regions should take into account the potential emergence of unknown animal tick-borne diseases that can be transmitted by imported ticks.
